Cardiopulmonary bypass (CPB) is a method that temporarily takes over the perform of the guts and BloodVitals SPO2 lungs throughout surgery, BloodVitals test sustaining the human blood and oxygen circulation. The CPB pump, painless SPO2 testing usually also named as coronary heart-lung machine (HLM), painless SPO2 testing deals with human lives. Hence, technical requirements are specifically high. A reliable operation of all utilized tools should be assured at all times. For painless SPO2 testing that reason, painless SPO2 testing combining movement measurement and air bubble detection constitutes a major BloodVitals SPO2 safety and consolation function. As the heart-lung machine takes over the operate of the heart and painless SPO2 testing the lungs, painless SPO2 testing it technically imitates the guts as a „pump" and the gas change of the lungs. The HLM operates two major circuits: the venous circuit and the arterial circuit with further feed traces. The venous circuit is fed by venous blood originating from the fitting ventricle of the patient’s coronary heart drained into the venous reservoir, where it is processed and smoothly pumped back into the aorta of the human physique. The arterial pump takes over the full or partial pumping efficiency of the guts when required.

The pump, which is fed by the venous reservoir and instantly connected to an extracorporeal oxygenator, is the principle pump of the HLM
